Iii order that the relation-and location -of the several mechanisms of the machine may be clearly undcrstoomthe trucl or frame carrying these pa; will be first described.

The tram/ o or frame.

The truck shown is of the wheeled type, being mounted upon a main wheel 1 and transport wheels 2 and 3.in front and at the side thereof respectively, and is adapted to be drawn or pulled by any suitable soprce of power, such as horse power or a tractor,

the operator occupying a seat 4 upon the front end thereof substantially over th transport wheels 5; g a

This frame 1s shown to be formed of angle material and to comprise a plurality o longitudinally die posed members 5 down-,

wardly bowed bet Ween their ends and converglng at their f ront ends "where they are rigidly attached pogether at a point over the tongue truck carrying the transport Wheels The rear ends ofthese members extend rearwardly substantially parallel'to each other on opposite sides of the main wheel 1. ;A. transversely extending frame member 6 is rigidly attached to these frame a members 5 at'a point in front of the main it is bent at right angles or attached town other frame memt er to form a third longi- Qtudinally extending member. 7 Which"ex- I tends parallel to the rear ends of the memhers 5 and is connected thereto at its rear end and in back of the mam wheel 1 by a second; transversely extending member 8 in such amanner that the whole forms a rigid frame.

In this frame the axle 9 of the main wheel is journaled in slitable bearings 10. The

grainward end of this axle is seated and positioned in thestubbleward end of a mus-I versely extending tubular axle member 11 which also receives ina like manner in its opposite end the stubbleward end of the axle 12 of the transport wheel 3. It is to be noted that as shown in Fig. 1 both of the axles 9 and 12 are attached to the tubular axle member 11 by means of bolt connections 13 in such a manner as to lock the axles thereto. Attention. is further directed to I i the fact that the tubular axle member.- 11

is .itself rigidly connected to the adjacent frame member by means of converging rigid braces 14 fixed to the inner member 5 at points on opposite sides of the main wheel 1 and havin their gruinward ends attached to a single racket 15 carried on the member 11 intermediate its ends and locked.

Upon the longitudinally disposed front ends of these two members fland 18 the cuttingrnechanism is sup- Tlie cutting mechmism.

cutting mechanism is located on the grainward side ofthe operators seat 4 and "slightly in the rear thereof, in front of the I .transport wheel 3 and on the grainward 3 frame, and reel 22 journaled above/the side of the main Wheel, and, as in the usual construction,

a line of draft.

extends transversely across the It comprises a transversely disposed fra ine 19,'a knife bar 2O recipr'ocable thereon between the guard fingers 21 carried. on the frame. [As shown in Fig.1, the imif ao is driven from the. wheell throu' h a:- pitman connection 23. and a shaft 24. his shaft .24 carries asprocket 25 on its rear end which engages a cha'in26 and is rotated by the latter; the chain being driventhrough a beveled gearconnection 27, journaled in a bracket 28 carriedby the frame, and itself driven through achain 29 suitably connected to the power: sprocket 30 on the grain- I ward side,of themain wheel; "As; shown in Fig. 1, this powerconnectionis controlled by a spring clutch controlling mechanism 31; a lever 32 of the usual detent type and operable from the'operators seat 4, being provided to throw the cutting mechanism into or out' of connection with themain wheel. The reel 22 is'carried'o rt'a trans ing'the operator in raising the same.

shown 1n Fig. 2, this lever is adjustably" mounted in longitudinally adjustable bear ings 34 carried on vertically adjustable supports 35 fixed to the cutter frame find-braced on the axle member 1l-by a rearwardly ex-' tending brace 36. As shown in Figs. and 4, this reel is operatively connected to the main wheel through the some power connection as that which drives the cutter mechanism and' is controlled by the same controlling lever 32; the counter-shaft 37' carrying a sprocket 38 on its rear end which engages the chain 26 and is operatively connected to the shaft 33 by a bevel gear'con nection 39. v This whole cutting apparatus is adjusted vertically with respect to the machine frame, *bel-ng movable.v into any desired. position about pivot on the axles 9 and 12 by an "operating lever 40, so that it can cut the grainat any desired height or be adapted to use on uneven ground; a spring 41, between the axle member 11 and the frame, normally tending to hold the cutting mechanism in a predetermined elevated positionand assistpivoted at 42 to the upturned front endof the pivoted support 18 and is provided with a spring detent mechanism operable by the operator to lock or unlock the cutting mechanism in any desired position upon an upstanding arcuate standard 4 3 fixed to the frame and having a plurality of holes 44 therein adapted to receive the latch 45 of the detent mechanism when the thumb lever thereof is released. As shown in Fig, 2, this latch is carried by a suitable bracket 46 attached to the lever 4.0 at a point intermediate its ends and provided with an extension 47 through which the pin is movable,

as well as space lugs 48 movable in sliding engagement with the opposite sides of the stan aid to guide the 'lever as the same is moved, about its pivot. In order to give increased rigiditY.-to the frame of the machineand to the standard 43, the lower end of the latter -i s preferably extended transversely across the; frame members 5 and rigidlyattached thereto as shown in Fig. 1.

As the grain'is cut by the .knife 20, it-is I carried along on" a :travelin' yeyer mechanism in a stubb ewardjand upxward direction'and is then turned in a. rearwand direction substantially at right angles theretd and delivered to the threshing mach nia The courage r mechanism,

Receiving the grain from the stubbleward 0. end .of this conveyor 49 is a second trans versely extending conveyer 54 rotatably mounted on rollers 55 journaled in an ad u'st'able frame 56 pivoted to the extension l 2on the cutter frame and supported by -25. and ,slidable along a ledge 57 son the :adjacent;conveyer,frame 58,, This-apron or conveyer'5lis likewise rotated from, the main wheel 1 through the power sprocket on the wheel 1, having a sprocket 59 driven 30 from "the chain 26. As shown in Fig. {1, this apron or conveyer 54 is considerably-shorter than the conveyor i9, being disposed in a.

substantially horizontal frame across the front 01" the machine and substantially op- 35, posite the main-wheel 1. I

As shown 1n Figs. 1 and 4,this conveyer fceds'the grain out upon a third conveyer 60 traveling in a directional: r-Ightangles theretoand feeding the grain in a rearward direction with its hea ls to the rear. Th s conveyor 60 is supported on the front open end of the conveyor frame 58* in a plane parallel to the line of draft outside of the 1 main wheel *1, and is driven by suitable. rollers 61 rotatable from thelmam wheel 1 through pinions 62, 63, chain and.sprocket-.,; v s whichis shown in Fig. 5 to comprise a.p1u

connections 65,66, and a shaft 6.7 jouriialed in the frameand driven-bythe stubbleward power sprocket 68 on the main wheel. Asa. shown in Fig. 3, this conveyor is disposed at an angle to the horizontal, having itsrear end inclined slightly upward and protrading under a fourth eonveyer 69.

' This fourth co nveyer 69 -,is rotatably mounted on rollers 70, 71 and,driven from v the main wheel 1 bythe pinion 63.- As

shown-in .Fig, 3, this conveyor is shorterl 7 than the conveyor 60 and provided with rollers; of'fdiiferent diameters disposed sub- 60 stuntiallvparallel.tothe ground and with the largencne in the rear, th e fdirection of rotation of these, rollers being such that the conaeyer 69 cooperates with the conveyor 60 ,iin sucl manner that the grain fed irom w madame lat .is

distributed evenly and downwardly'heads first to the knives 72 of the thresher cylinder 73.

The threshing mechanism.

As the grainis fed in by the conveyers 60 and 69, it is acted upon by the threshing' mechanism, the str aw being ejected at the rear of the latter and the threshed grain being fed in a gruinward direction trans-' versely of the frame to the separator carried on the frame between the main wheel 1 and'the transport wheel 3.- c

This threshing nechanism is shown to be inclosed in a suitable framework or box 74 mounted outside the main wheel 1 and parallel thereto upon Jhe stubbleward lon itudinal frame member 5, the longitu inal frame member and the trans'verseframe member 6.; As shown in Fig.3, it comprises a. cylinder 73, hating the usual teeth 72, rbtptably mounted in the frame 74in such a manner as to enable it to coiiperate' with an underlying grated concave 7 5 likewise supported 1n the fr M118. This cylinder 73 is 9 mounted upon a shaft 76 and rotated through gearing connections 77, 78 .and 79 dr1ven from the main wheel: l-through the plnlon 33 and the same chain and sprocket oonnectlons which drive the conveyers 60 5 and Adjacent thecylinder73 and suit ably oumaledin .tl 1e thresher frame 74 at a point above the cylinder and inthe rear.

thereof, is a suitable beater. 80 =which rotates in-the same direction as the c linder and acts upon thestraw fed out, t erefrom to beatthe same and also eject the same upon" the straw rack 81. As shown in Fig. 3, this beater is mounted upon a suitable shaft 82 ournaled 1n the th resher frame and driven 165 thrbugh a chain and sprocket co'nnection83 operativelyconneczed to the main wheel 1 through, 5 aced' sp POOkBtS'Bd, 85 journal'ed upon'the ttom of the frame. i At vpcint between. the straw rack. 81 and 11 0 the cylinder 73, a grate 86 is provided,

In order that'the chat? and refuse separated from. the grain by the fan 120 may be suitably deflected to the side of the Ina-- chine as it is blown out through the open end of theseparatorpa curved or are shaped deflector 129 is provided upon the upper surface of a slanting member 130 pivoted at its rear end between the sidewalls of the separator parts and extending substantially acrossthc mouth of the same. As shown in Fig. 6, this pivoted i'n'ember 130 is provided with depending parallel'flang'es 131 on its opposite sides and its free front end is supported upon and freely movable longitudi-- 'nally of a chute 1352 attached to the cutter frame 19 and extending upwardly and rearwardljv therefrom. In order that the heads and partially threshed grain, falling through the screens 118 may be again rewhich'pfiojccts up into the path ofthe provided. which mai' turned 'tothe thresher to separate the grain completely therefrom, the member 130 is provided witha rearwardly extendmglip draft-to a suilicient degree to intercept the heavier particles blown out thereby and dcfiect' the same downward upon a sliding, second 01' under chute 13% supported atits free end upon the bottom of the chute 132, and supported at its upper-cite end by a'trans' versely extending shaft or pipe 135 carried in suitable brackets 136 on the walls of the separator box. It is to he noted that means are thus provided which deflect the chaff and dirt to theside of themachine without permittin it to return to the apron 419 and that supp .emental means re provided which deflect thaunthreshed grain or heads ,and cause them to pass through the chute 13 1 to the conveyer -19 in such a .rnanner that they may again pass thrmgh the thicsher. It is further to be noted that by the provision oi. the sliding: chute connection means are sit. the allele in the desired relation "in any 1msition of the ML justable cutter mechanism.

In order tlui t uniform cleaning may be ob tained despite ariations in the speed of the n' iechiue and tlicre'lrm'e otthe fan 120, means are provided for Mini-sting the screens 118 in the separator box. in order to permit "I fluent-cit these ax 1 1llil3(i in, a miltahlc .1

As heretofore described, the rod or shaft'135 is supported in a bracket 1%. This bracket is preferably substantially are shaped and provided with a plurality of teeth 140 .on one of its sides and an arcuate slot run-i ning along the name in which the rod or sl iaft 1.35 may be adjusted desired,'carrying withvit the links 139, and therefore the free end of t 1e screen frame 137. This adjustment is obtained through a second link connection AL-having a slotted end through which tlle end-of the shaft 135 extends, which is pi voteol'at 14:2 to a crank 1 13 and operated thmugh a link and crank connection 1-14; by a lever 145 mounted on the machine frame a ij acent the operators seat. As-sliown in Fig. (3, the link 143 is pivoted to a shaft 116 journaled in the separator box and 'providec. with an arm 1417 protruding at substantiaily right angles to the link M3. This arm'l-i'? is provided with a 'flat upper edge or llange 1&8 underlying the shaft or rod135 and a coiled spring 149 is connected between the shaft 146 and the rod1135-in such a manner as to normally hold the parts under pressure. Obviously,

when the lever 14:5 is actuated to throw the link 1 13 in the direction indicated by rod 13-35, and therefore the chute 134 vand screen carrying frame 137, to be adjusted to any desired posilion in the bracket 136. It

'is to be noted in this connection that. since the chaff deflector 130is pivoted to the separator box 112, it will remain stationary during the movement of the screen frame 137 and the chute 134 that the amount of 1'10 chafi' discharged may be varied at will by varying the position of the screens. This feature is of decided importance where the such, for instanre, as those developed 'by the main wheel when the machine passing over uneven ground; the main wheel obviously being rotated more rapidlywhen going down the llill tlian when going up ,the I hill, and the fan necessarily being drivenu l zd faster or slower as the speed of r'otationof the main wheel v lJilBS. It is to be noted that in this imp'i'ovcm ent uniform cleaning-is ob-,.. tained regardless of variations 1n speed and that any desired proportion of the chaff inay'1'25 be returned to the thresher upon. 'the'opera-j tion oi? me is readily accessible to the operator of the machine. r a Both thetliresh ng and. separating mech 1111131115 heretofore discussed are driven "mm III f the power sproeket- 68 and are controlled through mechanism controlling the connection of their driving mechan sm with this sprocket. v p p The power controlling mechanism This mechanism is carried upon the rear of the machine frame at a point beyond the main wheel 1 and is controlled through a lever operable from the operators seat at the 'front' of the machine. .a v

As shown in-Fig. 1, the power shaft 67 is journaled' in bearings 150, 151 carriedfupon the rear of the frame, and iscontrolled by a' movable clutch member 152. Thiscljuteh member 006 rates. with a second clutch member'153 reely' rotata'ble on the shaft 67 and isnormally held in engagement with this "driven member 153 bymeans of a single spring 154 encircling the shaft. As in the usual construction, the movable clutch member 152 is splined to the shaft and movable longitudinally thereof realise its active surfaces to engage the surfaces of the driven member. The operating. mechanism for this clutch member 152 controlling the connection of the power shaft .67 to the mainwheel, comprises a transverse rod' 155 journaled in bearings 156 upon the rearof the frame and having a forwardly projecting arm 157-.

extending-into a radial groove 158 on the clutch member 152. This rod or shaft 155.

' is also provided with an upward extension 159 on its grainward end which is connected through aflongitudinally extending link 160 to a .foot leverjlfil journaled in? the frame adj'acent the operators. seat in isuch a manner that when the foot lever is thrown in one direction or the'other, the clutch member152is thrown into orvou't of engage ment with the driven member 153 and the several mechanisms connected to the power shaft 67 are connected to' or disconnected from the main wheel.

, In order that the coiiperation of the several mechanisms when the machine isqoperating, may be clearly understood, the operation of the whole machine will now be,

briefly described. 7 p

, Ojnemtz'on of .the complete machina' Let us assume that the machine is being drawn toward the grain. -By manipulating the lever 40 the level of the platform 19 of the cutting apparatus is so adjusted that. the knife 20 will cut the grain at the' desired height; the platform being swung about pivot on the axle member 11'. By manipu ating the lever 32 tothrow in the clutch 31', the conveyers 49 and 54 are set in motion, moving in a transverse direction across the frame, and the knife 20 and. reel 22 are likewise setin.motion.. To setthethreshing mechanism in operation, the operator presses down the 'foot lever 161, throwing in the clutch member 152 and connecting the aprons 60 and 69, the threshing mechanism and'the'separator mechanism to the main wheel through their connection to the shaft 67. As the machine moves forward the grain is acted upon in the usual manner by the reel and cutting mechanism and fed transversely of the frame upon the apron 49 with its heads to the rear, passing up on the inclined end of the eonveyer 49 and onto the second conveyer 54 which continues to feed the grain transversely of the conveyor-69 which com resses the same andremoves bunches there rom in such a manner that it is evenly distributed, heads first, to the threshing cylinder 73. This cylinder acts upon the grain-in the usuaL manner, the v threshed grain falling through the concave 7 5 and the grate 86 onto the grain pan 104, while the straw is fed outward by the beater 80 to the straw rack 81 by which it is thoroughly fiufied out and separated so that any grain remaining therein falls downward upon the bottom of the rack. carrier and is likewise diverted to the grain pan. ()b'vition's, the rack carrier may be adjusted to different heights means of the adjustment of the connection 92. Due to the connection of the grain .pan 10st to the/main wheel 1 and the mounting of the same, this grain pan is given a to and fro rocking -1OO ously, when working under different condimovement about its pivots -10 in such a manner as to feed the grain rearw'ardly to the auger 110, which in turn transmits it in a' transverse direction to the separator elevator 114. This elevator carriesthe grain "to the top of the 'separator.112 whereit is evenly distributed'across the screens 118 by the auger being cleaned as it falls between the screens by the action of the fan 120, the chaff "and dust being blown out lthrt iugh' the open end of'the separator box, While" the clean grain passes down over the weed-screen 121 to the grain auger 122 and by the latter is conducted to the delivery elevator 123. Should the machine be operating upon a down or up grade, the increased-or decreased speed-of rotation of the fan' and its tendency to blow out grain through the open endof the separater box or to fail to clean: the'grain thoroitghly, is

compensated for by the adjustment of the screen frame 137 through manipulation of the hand lever 145; the screen frame being I somoved about pivot 119as to bring the i the spaces between the screens.

the chaff and dirt blown out through the deflector 133 to the desired position opposite Obviously,

open end of the separator box will be deflected to the side and deflected upon the ground by the deflector 129, while the unthreshed grain will be blown out-upon the chute 134 and again delivered .to the apron 49.

It is to be notedthat in this construction a very compact machine isfiprhvided which may be readily turned ort. maneuvered as desired in the field and "which may be readily transported to and from the field without making it necessary to take down any of the machine. for transport and set it up again before it can be operated. l urther, the weight of the machine is so distributed that the far greater proportion of the same rests upon the main wheell in such a mannor as to increase the traction of that wheel.

and reduce waste draft. Further, due to the location'of the several arts of the mechanism and the, improvet manner in which V ing conditions such as those found in service.

By the'provisiolr'of the improved feeding mechanism for the thresher, the liability of the grain becoming lodged in such amanner 5 as to choke at the mouth of the cylinder chamber is entirely obviated, the upper apron operating to compressthe grain and feed it evenly, heads first, diiectly into the path .ofthe cylinder teeth.- Further, by the provision of: the improved grate and straw rack, means are, provided which feed the straw out rapidly from the cylinder without clogging andwhich at the same time thoroughly agitate the same in sucha manner that the kernels of grain are eflectually separated therefrom before the straw' is delivered upon the ground over the rear end of the straw rack. It is further to be noted that the grate, grain pan and straw rack are of an exceedingly simple and rugged construction which may be rcadily'and cheaply .manufactured. By'the provision of the in1- proved separatingmechanism, tllfi'glflll'l 1s effectually cleaned and all variations in the speed of rotation of the fan are effectually overcome; all, or part of the chafilbeing returnable to the cutter apron asdesired in ordtr to insure saving all the grain. It is further to be noted that due to the sliding connection of the cutting mechanism and the grain screens, either of these elements maybe adjusted independently without interferi with the other;
